The Federal Investigation Agency had lodged an FIR against them in connection with the 26\11 terror strikes.

Both Lakhvi, Shah and Hamad Ameen Sadiq, a key terrorist linked to the Mumbai terror attack, are linked to the LeT and have been named in the FIR lodged by the FIA, according to western diplomatic sources.

Though Shah and Lakhvi were arrested during a raid by the Pakistan army [Images] near Muzaffarabad in Pakistan-occupied Kashmir in early December, they were handed over to the Inter Services Intelligence for investigations, they said.

Sadiq was taken into custody by the FIA after its investigations into the dossier given by India on the 26\11 Mumbai terror strikes, Interior Ministry chief Rehman Malik had told reporters on Thursday.

Sadiq, who hails from southern Punjab and was arrested in Karachi, is being seen as a key LeT operative, though he had not come under the scanner of India.
